FRANK MUNSEY, OF PERSIA, TENNESSEE.

PLOW.

Specification of Letters Patent.

Application filed September 23, 1914. Serial l [0. 863,167.

To all whom it may concern:

Be it known that I, FRANK MUNSEY, a citizen of the United States, residing at Persia, in the county of Hawkins and State of Tennessee, have invented certain new and useful Improvements in Plows, of which the following is a specification.

My invention relates to plows.

The primary object of my invention resides in the provision of a novel cutting means associated with the beam of a plow for facilitating the effective operation of the plow in the ground,the cuttingmeanshaving novel means associated therewith for allowing the sameto be moved into engagement with a plow share carried-by thebeam when the cutting means engages a rigid object in the ground for facilitating the uninterrupted progress of the plow.

Another object of my invention resides in the provision of a novel meansdor mounting the cutting means which in this instance is in the form of a colter, the mounting means being removably connected with the beam of a plow'for varying the pitch of the colter to the ground without disconnecting any of the parts.

A further object of my invention resides in the provision of a novel means for adjustably connecting the cutting means with themeans foro crating the latter for varying the pitch 0 the cutting means or colter to-the ground and also rovidesnovel means for facilitating the ad ustable mounting of the operating ,means.

A still further object of my invention resides in the provision of a device of the character described that is simple in construction, eflicient-in-operation and one that can hemanufacturedand placed on the marketat a minimum cost.

Other objects aswell as the nature, characteristic features and scope of my invention will be more readily understood from the following description taken in connection with the accompanying drawings and pointed out in the claims gforminga part of this specification.

In the drawings Figure 1 is a sideelevational view of my l v n, the dott ne show ngit .P

tion assumed by the colter when the bit thereof comes in contact with a rigid object.

Fig. 2 is a transverse sectional view taken on the line 2-2 of Fig. 1.

Referring .nore particularly to the drawings in whirh similar reference numerals designate like or corresponding parts throughout the different views, I provide a beam 1 formed preferably of wood, though not necessarily, which beam has a standard 2 depending from the point adjacent the rear end thereof, the standard having a plow share 3 rigidly connected to the lower end thereof for or gagement with the ground. A brace rod 4 is provided to aid the securement of the s andard and share to thebeam, the respective ends of which rod are engaged by nuts: 5, only one of which is shown inthe drawings. In order to guide the plow ,during movement and to fac litate the efficient operation of the same, I have provided handles 6, th inner ends of which are rigidly connected to the plow share from which point the handles diverge rearwardly, the handles being connected by suitable cross pieces 7 for strengthening the same.

Pivotally mounted on the sides of the beam at a. p( int substantially midway the forward end if the beam and the standard 2, by means of a suitable fastening device, preferably a )olt 8 are a pair of T-shaped supporting p: ates 9, the offset ends being positioned ad; acent the forward end of the beam, the opposite or rear ends of which Patented Feb. 20, 1917. I

plates have pvotally connected thereto my improved colt 5r. The colter in this instance comprises a head formed of angularly bent head plates 11! and a substantially triangular bit 11 carried thereby. Bolts 12 are extended through the rear ends of the T- shaped plates 9 and arranged in engagement with the upper ends of the head plates 10 for pivotally connecting the latter thereto, 'the lower encs of the head plates having their forward marginal edge arranged in alinement with the upper end of the cutting 5' edge of the colter and rigidly secured thereto by suitable fastening devices preferably rivets 13.- In order to vary the pitch of the colter to the ground, I have connected the offset portions of the T-shaped plates by means of a bolt 14 and a nut 15, the bolt operating in the arcuate slots 16 in the plates. By this arrangement the disconnecting of any of the parts for varying the pitch is obviated.

Suitable draft actuating means has been provided for causing the colter to assume a position for facilitating the uninterrupted progress of the plow and in this instance consists essentially of a draft clevis 17 pivotally mounted on the forward end of the L order to vary the pitch of the colter to the beam by a suitable fastening device 18, the clevis having a link 19 movably mounted on its vertex for facilitating the removable engagement of a draft device 20. Pivotally connected to the opposite sides of the clevis as indicated by the numeral 21 is a connecting rod 22, the latter terminating in a forked extension which is pivotally connected to the depending elongated ear 23, the ear being carried by a clevis 24, which is pivotally and adjustably mounted in one ofthe openings 25 in the beam by means of a suitable fastening device 26. In

ground to a greater extent than that capable of the adjusting arrangement of the T- shaped plates 9, I have provided a link 27, the respective ends of which are bifurcated d and pivotally mounted in the adjacent lower end of the car 23 by means of a suitable fastening device 28 and in one of the uniformly spaced openings 29 in the colter bit 11 by means of a suitable fastening device l l 30. In order to facilitate the efficient operation of the colter when the same comes in contact with a rigid object, I have found it expedient to arrange the lower substantially pointed end of the plow share 3 so that ,the point of the share will be arranged in alinement with the cutting edge of the colter bit, the share also serving as a brace for the bit.

The operation of my invention is as follows:

When the colter 11 which clears a passage for the plow share during the forward movement of the latter comes in contact with a rigid object on the ground, the bit will be forced backward and placed into engagement with the lower end of the plow share as shown in the dotted lines in Fig. 1. Simultaneous with this movement the clevis 17 will assume a position as shown in dotted lines in Fig. 1, the clevis 23, rod 22 and link 27 will assume the positions as shown in dotted lines. of this operating mechanism, the forward movement of the plow will be uninterrupted. The bit 11 will, after coming in contact with the plow share, ride upon the objects and pass over the latter, whereupon the link 17 will assume its normal position simultaneously causing the bit to assume its normal position.

Because of the arrangement,

Although. I have shown and described the preferred embodiment of my invention, I desire to be understood that I am not limited to the exact details shown; however, great stress is laid upon the arrangement and construction of the colter and having the operatin mechanism associated therewith for facilitating the eflicient operation of the plow.

From the above description taken in connection with the accompanying drawings, it can easily be seen that I have provided a device that is simple in construction, containing but a few simple parts that can be cheaply manufactured and assembled and when assembled can be placed upon the market and sold at a minimum cost.

It will be understood that the above description and accompanying drawings comprehend only the general and preferred embodiment of my invention and that various minor changes in detail of construction, proportion and arrangement of the parts may be made within the scope of the appended claims and without sacrificing any of the advantages of my invention.

Having thus fully described my invention, what. I claim as new and desire to secure by Letters Patent, is

1. A colter including a head and a bit, means for adjustably mounting the head, and draft actuating means adjustably con nected to the bit for allowing the bit to move rearwardly when it engages a rigid object in the ground.

4. A colter including a head and a bit, means for adjustably and pivotally mounting the head, draft actuating'means including pivotally mounted clevises, a rod having its respective extremities pivotally connected to the clevises to permit of the clevises to move simultaneously, a link pivotally connected to the rear clevis and adjustably associated with the bit to permit the bit to move rearwardly when it engages a rigid object in the ground,'substant1ally as described and for the purpose set forth.
